Feature Request: Magnetic Compass Direction Photo Metadata Tag

[code-goat]

Wonderful work, thank you! I've been needing something like this for a long time! I have a major use case that requires photo filenames to include the compass direction that they were taken from. How difficult would it be to add the exif/metadata tag for "GPS Img Direction" and/or "GPS Img Direction Ref" to the replace/insert options?

Thank you for all your work!
